Great marble. I would, however recomend geting the Mega Marble Net "mars".Also, in the picture it looks clear but when we got it it was opaque.

Mars Marble review 7/29/2010

Reviewer: Ruth Bazire (Salisbury, Wilts)

The Mars marble is a very mysterious and exciting looking one. I love it because it looks so fantastic, and like my other hundreds of marbles it shoots well (as it should, being so war-like!). People have asked me for a trade deal, but every time I have said the same answer - no. It is very well designed and the golden ticket is creativity.
